You're off-base in almost every regard.

>It's inarguable that consumers got lower prices, substantially lower prices. That's increased their standard of living.

It's a multifaceted issue. Yes, Walmart sells cheap stuff, but that's not the company's only impact on the standard of living. The middle class has been steadily shrinking since the 70s, consistent with the rise of Walmart http://www.huffingtonpost.com/2013/06/06/middle-class-jobs-i...

> You can argue that Walmart hurt the standard of living of the Americans (less than 1% of US employees) who actually work for it.

The key issue is not Walmart's employees, but rather the employees of the companies they source from.

> Walmart big advantage wasn't labor costs, it was scale and inventory management from day one.

Once again, it's about the cost of the goods they sell that has a bigger economic impact than their direct labor cost. What goes into the cost of the goods they sell? Labor costs of their suppliers. What did they do after their advantage of scale and great inventory management management eroded? They started sourcing products from markets that were fueled by cheap labor i.e. not the USA. Sam Walton has been rolling in his grave for years: The first true Wal-Mart opened on July 2, 1962, in Rogers, Arkansas.[18] Called the Wal-Mart Discount City store, it was located at 719 West Walnut Street. He launched a determined effort to market American-made products. Included in the effort was a willingness to find American manufacturers who could supply merchandise for the entire Wal-Mart chain at a price low enough to meet the foreign competition. --> https://en.m.wikipedia.org/wiki/Sam_Walton

> I'm always struck by how good the products are and how amazing the prices are.

You're probably one of very few

When a Walmart opens, it knocks out about half the jobs in a small town. It doesn't replace that number. It also pays so low many of its employees are on welfare. Companies like WalMart are subsidized by the taxpayer. Repeat that across thousands of stores to get enormous impact on economy.

Add downsizing, consolidation, price gouging (i.e. Koch's, oil), and offshoring to get an even bigger one across the board. The Recession was a given with buying power always going down while costs always go up.

Walmart has certainly not been a huge boon to the middle class, if they have been, we have not seen any evidence of it. The middle class is shrinking. So if this is true, that means the middle class is doing MUCH worse than realized.

From what I've read, Despite the cheaper prices, there was a net loss in jobs and significant damage to small business-resulting in higher losses in the local economy than gained from cheaper product. I don't know if there's enough evidence of all of that, but it seems logical.

Also you're ignoring the local economic impact of closing small businesses. It's not just the small retail store employee that loses out. Small businesses close-that means there's less need for accountants, cleaners, advertisers, real estate, etc. Walmart does all of this at the corporate level. This results in even more, well paying job loss, and sets off a spiral that destroys these communities.

> And it's products are as good or better as the competitors.

Sounds like confirmation bias to me. Nothing I ever see or buy from walmart has ever been quality, but I couldn't present that as evidence.

>Walmart has been a huge boon to the middle class. It's inarguable that consumers got lower prices, substantially lower prices. That's increased their standard of living.

Only when thinking in first-order effects. How about the city businesses it destroyed, and thus the standard of living associated with the families that owned them and the whole support system? How about the power it affects upon manufacturers -- and thus to the people that work there?

I think Walmart has damaged the economy a lot. Maybe smaller companies are less efficient but Walmart has destroyed a lot of small business that provided fairly stable jobs to middle class people.
